applications:

although sildenafil (viagra), vardenafil (levitra), and tadalafil (cialis) all work by inhibiting pde5, tadalafil's pharmacologic distinction is its longer half-life (17.50 hours) – compared to sildenafil (4.0–5.0 hours) and vardenafil (4.0–5.0 hours) – resulting in longer duration of action, and so partly responsible for "the weekend pill" sobriquet. furthermore, the longer half-life is the basis for current investigation of tadalafil's daily therapeutic use in relieving pulmonary arterial hypertension. sildenafil is approved in several world regions as a thrice-daily therapy for pulmonary arterial hypertension.
